This app calculates the time it takes for your egg to be perfectly cooked, just enter the mass and temperature, as well as your altitude and this app will provide you with a timer and an alarm so you can eat perfectly soft-boiled eggs every time!

The idea is that it takes a certain amount of time for the whites to cook until they are firm while leaving the yolk nice and runny, which is what the app computes for you using a clever formula. For some more information on how this works go check out my website to find some details on the physics as well as some references!
